VEHICLE-GEAR.

SPECIFICATION forming part of Letters Patent No. 356,821, dated February l, 1887.

Serial No. 2162805. (No model.)

To all whom it may concern:

Be it known that I, GEORGE G. BURGH, a resident of the town of Groton, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in VehicleGears, said improvements being described in detail in thc following speciication, and illustrated in theaccornpanying drawings.

My invent-ion is in that class of gears in which socalled cranked axles are used; and it consists of certain improvements in the'means employed to secure the spring to said axles. It also relates to the method of attaching the thills and sandhoxes.

One object of my invention is to provide a spring-attaching device which shall allow free endwise pla-y of the spring when depressed, and which requires no special lugs or projections forged integral with the axle, my device being formed preferably of malleable iron or cast-steel and adapted to be attached tothe axle by clips of ordinary construction.

Referring to the drawings, Figure lis a rear eleva-tion of au axle having its spring attached by my newlydnvented device, and Fig. 2 is a top View of the axlewitb said attaching device removed. In Fig. 3 I have shown a side elevation and an outer end View of the said springattaching device considerably enlarged.

The reference letter a indicates an axle cranked sidewise, as at b, and also depressed in a plane at right angles `to crank b, (see c, Fig. l.)

d indicates a plate oi about the Width of the straight portion of the axle which it is to engage, and having formed integral with it a transverse rib, e, transverse lugs h, projecting upward to form a Jchill-coupling, and a sandbox, i. The rib c is drilled to receive a bolt, it, to each end of which is hung alink, fm, provided to receive and support one end of spring n. Said spring extends upward. past the cranked portion of the axle, as shown in the drawings, being substantially the shape of the upper halt' of an ordinary elliptic spring.

With the spring secured as described, I am able to hang the body much lower than with a straight axle and elliptic spring.) The plate d has integral angular extensions o on its sides, which straddle the square portion of the axle 5o and prevent lateral displacement, and said plate is firmly clamped to the axle by asingle clip. (Indicated by dotted linesin Fig. l.) The sandbox z' is cupped to slip over the axle-collar i', and thus prevents endwise movement of 55 the plate.

It Will be obvious to a mechanic that the thillcoupling lugs z. could be dispensed With and a very satisfactory result attained; but I prefer to use the complete device, substantially 6o as described, as it reduces materially the cost of a vehicle and provides a strong and simple means for accomplishing the three desired resuits-i. e., an adjustable spring attachment, a thill-coupling, and a sand-box.

Having thus described my invention, I claiml. In combination with a semi-elliptic spring and a laterally-cranked axle of the form reerred to, a plate adapted to rest on the straight portion of the axle adjacent to the arm, having pivotally secured thereto springsnpport ing links, as described, and having formed as an integral part of said plate a sand box adapted to slip over the axle-collar, and a clip for clamping together the plate and axle, in the manner set forth.

2. In combination with asemiellipticspring and a laterally-cranked axle of the form referred to, plate d, having pivotally secured 8o thereto spring-supporting links, as described, and having both the integral thill-coupling lugs h and sand-box i, and a clip for clamping together said plate and axle, substantially as set forth.
